The 27-year-old - world-record holder over 100 and 200 metres - had been expected to make his return on the track in the Czech Republic on June 17, but announced on Friday that would not be in attendance for that or for the Paris Diamond League meeting on July 5

Six-times Olympic champion Usain Bolt has confirmed his withdrawal from upcoming events in Ostrava and Paris as he continues his recovery from a foot injury.

The 27-year-old - world-record holder over 100 and 200 metres - had been expected to make his return on the track in the Czech Republic on June 17, but announced on Friday that would not be in attendance for that or for the Paris Diamond League meeting on July 5.

"As reported a few weeks ago, I had to miss some training in late March and early April due to a foot injury," he posted on his website, www.usainbolt.com.

"Thankfully, my foot is 100 per cent healthy now and I am back in full training.

"Unfortunately, due to the training that I missed, I am behind where I am at normally at this time of year and will not be ready to race in the Ostrava Golden Spike meet or Meeting Areva in Paris."

Bolt did not specify a new comeback date - with this summer's Commonwealth Games in Glasgow looming at the end of July - but vowed not to rush his recovery.

"I hope to be back in competition soon but how soon will depend on my training in the next few weeks," he added.

"It is important for me to take my time this year as I have three tough years ahead in 2015, 2016 and 2017 as I attempt to defend my world and Olympic titles.

"I definitely plan to compete this season and will continue to work hard with my coach, who I have the utmost confidence in to get me fit and ready to compete."
